YA Theme for YADR
#
# Mudasobwa yadr theme.
#
# Based on Agnoster theme from https://gist.github.com/3712874
#
# NB! In order for this theme to render correctly, you will need a
# [Powerline-patched font](https://gist.github.com/1595572).
#
# Authors:
# agnoster (original)
# digitalformula (modified for compatibility with Prezto - https://github.com/sorin-ionescu/prezto)
# mudasobwa (added right prompt for ruby environment, code cleanup etc)
#
# Original agnoster theme was written for Oh My Zsh - https://github.com/robbyrussell/oh-my-zsh
# The modified version by digitalformula required git-omz.zsh and get-short-path.zsh
# The code of latter is included here for convenience

#
# agnoster's Theme - https://gist.github.com/3712874
# A Powerline-inspired theme for ZSH
#
# # README
#
# In order for this theme to render correctly, you will need a
# [Powerline-patched font](https://gist.github.com/1595572).
#
# In addition, I recommend the
# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
# it has significantly better color fidelity.
#
# # Goals
#
# The aim of this theme is to only show you *relevant* information. Like most
# prompts, it will only show git information when in a git working directory.
# However, it goes a step further: everything from the current user and
# hostname to whether the last call exited with an error to whether background
# jobs are running in this shell will all be displayed automatically when
# appropriate.
### Segment drawing
# A few utility functions to make it easy and re-usable to draw segmented prompts
